Shown in Fig. 2 (a) and Fig. 2 (b), plunger unit 30 constitutes slender rod shaped unit through the both sides non-movable piston guide 34 at the bobbin 35 of the cylindrical portion of bringing into play function as the balancer guide.On bobbin 35 slidably outside embedding plunger 32 is installed, and also outer embedding is equipped with the plunger force application part 33 that is used for carrying out towards 16 pairs of these plungers 32 of exit wound of bullet all the time the application of force.
In addition, plunger guide part 34 is used for the slip channeling conduct to plunger 32, like Fig. 4 (a)～shown in Figure 5, alongst is being formed with rail portion 34a with bobbin 35 opposed inside.
As shown in Figure 1, this plunger unit 30 with the length direction of bobbin 35 and nail get direction parallel and make impactor 31 apart from handle 13 farthest the mode of (in other words, bobbin 35 than impactor 31 more near handle 13 1 sides) be fixed in the inside of shell 11.
Sidepiece at plunger 32 is formed with the impactor connecting portion 32b that is used to connect impactor 31.Impactor 31 is connected on this impactor connecting portion 32b, and forms, and along with the slip of plunger 32, impactor 31 also slides.
Shown in Fig. 3 (a) and Fig. 3 (b), in this plunger 32, have the bobbin hole 32e that is connected by above-mentioned bobbin 35 in central authorities, and the wall portion of the both sides of 32e is provided with guide pulley 32a in this bobbin hole.Shown in Fig. 4 (b), guide pulley 32a is the parts that in the rail portion 34a of plunger guide part 34, slide.Through this bobbin hole 32e and guide pulley 32a are set, plunger 32 is by the mode channeling conduct to slide along bobbin 35 and plunger guide part 34.
Shown in Fig. 3 (a) and Fig. 3 (b), be formed with highlightedly at the sidepiece of plunger 32 and be used for the first buckling parts 32c and the second buckling parts 32d that fasten with above-mentioned driving mechanism 20.The above-mentioned first buckling parts 32c and the second buckling parts 32d are arranged on and are provided with the opposite side (driving mechanism 20 1 sides) of a side of impactor connecting portion 32b.In addition, the first buckling parts 32c and the second buckling parts 32d are provided with mutual different height position (with the relative position of exit wound of bullet 16), that is, shown in Fig. 3 (b), the first buckling parts 32c is arranged on than the second buckling parts 32d more near the position of exit wound of bullet 16.Therefore, the first buckling parts 32c and the second buckling parts 32d are disposed at different position each other with respect to the glide direction of plunger 32.
Overcome plunger force application part 33 active force and on push away plunger 32 driving mechanism 20 constitute, possess a plurality of gears as shown in Figure 6.Above-mentioned a plurality of gear is rotated under the driving force of motor 17.Motor 17 forms, in trigger 14 starting during by operation, and detect through not shown microswitch plunger 32 move to the position of regulation before perseveration.
In addition, be provided with the control device (not shown) that possesses CPU and RAM etc.,, the driving of motor 17 controlled based on input signal from trigger 14 or microswitch through this control device in the inside of driver 10.
This driving mechanism 20 makes gear rotation in that plunger 32 is fastened under the state on the gear, push away plunger on thus.And it forms, and through the fastening of gear and plunger 32 is removed, with the active force of plunger force application part 33 plunger 32 is moved, and makes the impactor 31 that is connected in plunger 32 slide and nail is got towards the direction of exit wound of bullet 16.
Say that at length shown in Fig. 6 (a), the first torque gear 22 and the second torque gear, the 23 rotatable earth's axis are supported on the torque gear plate 21 that is fixed on the shell 11, constitute driving mechanism 20 through making the first torque gear 22 and 23 rotations of the second torque gear.In addition, the first torque gear 22 and the second torque gear 23 are compared with the second torque gear 23 along the glide direction alignment arrangements of plunger 32, and the first torque gear 22 disposes more near exit wound of bullet 16 1 sides.Thus, plunger 32 is lifted through the fastening successively of the first torque gear 22 and the second torque gear 23 gradually.
Fig. 6 (b) expression plunger 32 is positioned at the state (nail being got the state after finishing through impactor 31) of bottom dead center position.When the first torque gear 22 and the second torque gear 23 were rotated, the torque cylinder 22a of the first torque gear 22 fastened on the first buckling parts 32c of plunger 32.
Then, shown in Fig. 6 (c), plunger 32 is directly lifted to the top by the first torque gear 22.When the first torque gear 22 rotated to the position of torque cylinder 22a arrival the top, the fastening of the torque cylinder 22a and the first buckling parts 32c broke away from.At this moment, before the fastening of the torque cylinder 22a and the first buckling parts 32c broke away from, the torque cylinder 23a of the second torque gear 23 fastened on the second buckling parts 32d of plunger 32.
Then, shown in Fig. 6 (d), plunger 32 is directly lifted to the top by the second torque gear 23, and plunger 32 moves to top dead center position.
Thereafter, shown in Fig. 6 (e), when gear is further rotated, the second torque gear 23 rotates to torque cylinder 23a when arriving the position of the top, the fastening disengaging of torque cylinder 23a and the second buckling parts 32d.Thus, therefore plunger 32 is moved towards the bottom dead center position shown in Fig. 6 (b) by plunger force application part 33 application of forces.Thus, form, the impactor 31 that is connected in plunger 32 slides and nail is got towards the direction of exit wound of bullet 16.
In addition; In this embodiment; Plunger 32 generally forms, in the top dead center position standby shown in Fig. 6 (d), and starting when driving mechanism 20 is operated at trigger 14; Via the state shown in Fig. 6 (e) → Fig. 6 (b) → Fig. 6 (c), await orders at the top dead center position shown in Fig. 6 (d) once more successively.
That is, when trigger 14 was operated, the control device that receives its operation signal began the driving of motor 17.Thus, when gear rotated to the position shown in Fig. 6 (e), that follows closely squeezed into action.Then, motor 17 also still continues after the release to drive squeezing into of nail.As a result, when plunger 32 moved to the top dead center position shown in Fig. 6 (d), above-mentioned microswitch was pressed by plunger 32.When receiving the signal of this microswitch, control device is controlled, and makes the driving of motor 17 stop.
The plunger unit 30 of this embodiment possesses reaction absorbing mechanism, and it is used for absorbing the reaction that above-mentioned nail is squeezed into action.
As shown in Figure 5, this reaction absorbing mechanism constitutes, and possesses the balancer 36, the court that are mounted slidably in bobbin 35 and leaves the balancer force application part 37 of the direction of exit wound of bullet 16 to these balancer 36 application of forces.
In addition, balancer force application part 37 is to be disposed in the bobbin 35 and the spring mechanism that carries out work adopts the compression spring.Compare with balancer 36, this balancer force application part 37 disposes more near exit wound of bullet 16 1 sides, and the direction that exit wound of bullet 16 leaves in court is to balancer 36 application of forces.
In addition, in this embodiment, bobbin 35 is formed the cylindric of outer surface sealing, still, for example, also can slit or peristome be set on the surface with replacing, also can form shapes such as prism-shaped.
Then; Plunger 32 is discharged from driving mechanism 20, thus, when impactor 31 towards the direction of exit wound of bullet 16 slide and follow closely squeeze into action the time; The action of traction of wire 39 is disengaged, so balancer 36 is balanced device force application part 37 towards leaving the direction application of force of exit wound of bullet 16 and moving.
In this embodiment, be that the reaction force of the active force that produced through above-mentioned balancer force application part 37 is realized what reaction absorbed.Below, with reference to the action of plunger unit 30 structure that reaction absorbs is elaborated.
Fig. 7 is the figure of expression plunger unit 30, is the figure that expression plunger 32 is positioned at the state of bottom dead center position.Under this state, plunger 32 by plunger force application part 33 towards the direction application of force of exit wound of bullet 16 and become the state on the buffer 41 of the rubber system of being pressed against.In addition, balancer 36 is balanced device force application part 37 and becomes towards leaving the direction application of force of exit wound of bullet 16 state on the balancer retainer 38 of the rubber system of being pressed against.At this moment, wire 39 is roughly does not have lax tensioning state.
Fig. 8 pushes away on expression plunger 32 driven-mechanisms 20 and makes plunger 32 be positioned at the figure of the state of top dead center position.Under this state, plunger 32 is overcome the active force of plunger force application part 33 and on the direction of leaving exit wound of bullet 16, pushes away.In addition, along with plunger 32 by on push away, wire 39 is stretched, the balancer 36 that is connected in the other end of wire 39 be overcome balancer force application part 37 active force and towards the direction tractive of exit wound of bullet 16.
Under this state, shown in figure 12, shell 11 bears the active force of plunger force application part 33 and balancer force application part 37, becomes the state that power balances each other.
When the fastening of plunger 32 and driving mechanism 20 broke away from, as shown in Figure 9, the direction that begins from the state of Fig. 8 towards exit wound of bullet 16 at the active force lower plunger 32 of plunger force application part 33 moved.So the wire of tractive balancer 36 becomes slack before, therefore, balancer 36 becomes free state, and balancer 36 beginnings are moved towards the direction of leaving exit wound of bullet 16 under the active force of balancer force application part 37.
At this moment, shown in figure 13, by the application of force reaction force P1 of plunger force application part with squeeze into reaction force P2 and produce the reaction when squeezing into, applied and make the driver 10 will be from being driven into the power that parts leave.
But, in the driver 10 that this embodiment relates to, form, through the application of force reaction force P3 of balancer force application part, applying will be with driver 10 by being pressed in the power that is driven on the parts.That is, balancer force application part 37 carries out the application of force towards the direction of leaving exit wound of bullet 16 to balancer 36, therefore, in a side opposite with this balancer 36, produces reaction force in the part of supporting balancer force application part 37.That is, shell 11 generations with respect to driver 10 will be pressed into the power that is driven on the parts.
Therefore, the application of force reaction force P1 of plunger force application part and squeeze into reaction force P2 and the application of force reaction force P3 of balancer force application part cancels out each other has alleviated the reaction when squeezing into.In addition, for the reaction that can't offset with the application of force reaction force P3 of balancer force application part, can eliminate through operator's press load P4 (also can add machine weight sometimes).
The lax of wire 39 when squeezing in addition, is owing to the translational speed that the translational speed of plunger 32 is set for faster than balancer 36 produces.Promptly; Poor, the plunger 32 of the active force through pilot plunger force application part 33 and balancer force application part 37 and the weight of balancer 36 or resistance to sliding etc.; Set the translational speed of plunger 32 for faster than balancer 36 translational speed, therefore, wire 39 becomes slack because of above-mentioned speed difference.
Then, shown in Figure 10 (a), wire 39 is hanged up on pulley 40 with the mode that can become slack, and utilizes the space S channeling conduct that is formed by shell 11.Therefore,, also can pass through the space S channeling conduct, thereby not form and can hang on other parts even lax wire 39 breaks away from from pulley 40.
Figure 11 is an expression plunger 32 from the figure that the state of Fig. 9 is moved further, plunger 32 has just arrived after the buffers 41 state of (nail squeeze into action just finished after).As shown in the drawing, after plunger 32 had just arrived buffer 41, balancer 36 did not also arrive balancer retainer 38 and under the active force of balancer force application part 37, continues to move.That is, because the translational speed of plunger 32 is set the translational speed faster than balancer 36 for, therefore, balancer 36 arrives balancer retainer 38 after plunger 32 arrives buffer 41.Then, when balancer 36 arrives balancer retainer 38, turn back to the state of Fig. 7.
In this embodiment; Through in this wise to plunger 32 stop regularly with balancer 36 stop regularly to be provided with time lag, the impact absorption that balancer 36 and balancer force application part 37 are produced (generation of the application of force reaction force P3 of balancer force application part) proceeds to the ground formation till the release of squeezing into of nail always.In addition, utilize the impact of balancer 36 bump balancer retainers 38 on the reaction direction, to apply power, the timing that this reaction is produced is squeezed into after the release as nail.
According to above-mentioned embodiment, driver 10 can possess: impactor 31 is provided with the mode that can slide towards the exit wound of bullet 16 of the front end of the instrument of being arranged at 10, and constitutes with the mode of securing member being got from exit wound of bullet 1; Balancer 36 is provided with the mode that can slide with respect to the shell 11 of instrument 10; And balancer force application part 37, the direction that exit wound of bullet 16 leaves in court is to balancer 36 application of forces.Balancer 36 can constitute, and along with the slip towards exit wound of bullet 16 of impactor 31, is balanced device force application part 37 application of forces and moves towards the direction of leaving exit wound of bullet 16.
According to this structure; When knock-in tack, though driver 10 is applied with the power of leaving on the direction that is driven into parts, simultaneously; Through the reaction force of 37 pairs of balancer 36 application of forces of balancer force application part, be applied with the power of pushing driver 10 towards the direction that is driven into parts.That is, should " putting on the power of leaving on the direction that is driven into parts " cancel out each other suffered reaction in the time of to absorb knock-in tack thus with " power of pushing towards the direction that is driven into parts ".Therefore, can be squeezed into power fully with less pressing force, therefore, can be alleviated operator's fatigue with respect to being driven into parts.In addition, also be difficult for taking place being separated to being driven into the problem that parts cause damage because of reaction makes impactor 31 and nail.
In addition; If the length direction of bobbin 35 and nail get that direction is equal in fact, the glide direction of the glide direction of balancer 36 and impactor 31 (for example is equal in fact; The glide direction of getting direction angulation or balancer 36 of the length direction of bobbin 35 and nail in the glide direction angulation of impactor 31 in the scope of 0～15 degree); Then " put on the power of leaving on the direction that is driven into parts " and " power of pushing towards the direction that is driven into parts " can be cancelled out each other the reaction that receives in the time of can being absorbed in knock-in tack in fact.Therefore; In the such description of this specification and claim described " bobbin 35 (cylindrical portion 35) disposes with the direction of getting of nail (securing member) abreast ", " balancer 36 with impactor 31 slides abreast ", the implication of " parallel " is meant: the glide direction of getting direction angulation or balancer 36 of the length direction of bobbin 35 and nail and the glide direction angulation of impactor 31 are in the scope that 0～15 spends.
In addition, be preferably the spring mechanism of balancer force application part 37 for when the direction of leaving exit wound of bullet 16 is slided, carrying out accumulation of energy at impactor 31.
According to this structure, can produce " power of pushing towards the direction that is driven into parts " by the elastic force of spring mechanism.
According to this structure, can make balancer 36 and impactor 31 carry out interlock, the action in the time of can corresponding squeezing into and make balancer 36 work with physics mode.
In addition, balancer 36 also can slide with impactor 31 almost parallel ground.
According to this structure, because " putting on the power of leaving on the direction that is driven into parts " is parallel with " power of pushing towards the direction that is driven into parts " and be opposite directions, so the reaction can absorb knock-in tack effectively the time.
Driver also can possess: plunger 32 is connected with impactor 31; Plunger force application part 33 is towards 16 pairs of plunger 32 application of forces of exit wound of bullet; Driving mechanism 20; Constitute; Overcome plunger force application part 33 active force and towards leaving the direction actuation plunger 32 of exit wound of bullet 16; And the plunger 32 that will be positioned at the position of leaving exit wound of bullet 16 discharges, and makes impactor 31 slide and securing member is got towards the direction of exit wound of bullet 16 with the active force through plunger force application part 33; Rope band shape parts 39 (wire 39) connect balancer 36 and plunger 32; And changes direction end 40 (pulley 40), be used to change the direction that puts on the power on the rope band shape parts 39.Balancer 36 also can constitute; Along with plunger 32 moves towards the direction of leaving exit wound of bullet 16; Slided towards the direction of exit wound of bullet 16 by rope band shape parts 39 tractives; And, slide towards the direction of leaving exit wound of bullet 16 through the effect of balancer force application part 37 along with being released the plunger 32 that produces because of plunger 32 towards the moving of exit wound of bullet 16.
In spring drive-type driver, because the elastic force of the spring that is used to squeeze into, it is big that the reaction during knock-in tack becomes, but according to above-mentioned structure, can absorb this kind reaction effectively.
Rope band shape parts 39 (wire 39) also can be hanged up on changes direction end 40 (pulley 40) with the mode that can become slack.
According to this structure, balancer 36 can be by plunger 32 tractives.Therefore, become slack through wire 39, balancer 36 is discharged from plunger 32 (wire 39) and can be moved separately, can not receive the obstruction of plunger 32 (wire 39), and balancer 36 is balanced device force application part 37 application of forces.Then, the reaction force through this active force has produced the power of pushing towards the direction that is driven into parts, thereby can absorb reaction.
In addition, balancer 36 also can be arranged in and follow closely gets in the bobbin 35 (balancer guide 35, cartridge 35) that direction is provided with abreast and can slide.Also the plunger guide part 34 to the slip channeling conduct of plunger 32 can be set in the both sides of this bobbin 35.
According to this structure; Can dispose balancer 36 in the inboard of bobbin 35, and can be at the outside of bobbin 35 configuration plunger 32, therefore; Can concentrate and less constitute the plunger unit 30 that possesses reaction absorbing mechanism, can reduce manufacturing cost and reduce product size.
In addition, plunger unit 30 also can be fixed in the shell 11, makes impactor 31 apart from handle 13 farthest.That is, also can balancer 36 be arranged to than impactor 31 more near handle 13 1 sides.
According to this structure, can make impactor 31 be positioned as close to the opposition side of handle 13 1 sides, therefore need unnecessary projection be set at the opposition side of handle 13 1 sides.Because the opposition side in handle 13 1 sides is not provided with projection, thereby can adopt the method for using that makes chain-drive section 15 press close to wall as much as possible, for example can be applied as the fine finishining driver that need nail be squeezed into the bight.
In addition, also can constitute, through impactor 31 nail squeezed into after the end, balancer 36 also still continues to move.
According to this structure, can the reaction that utilize balancer 36 to carry out be absorbed the timing setting that finishes after impactor 31 is squeezed into end with nail, therefore, reaction absorbing mechanism is played a role until nail is squeezed into end effectively.
